A surgical port includes a port body having a lumen extending therethrough and a plate having an opening. The port body may be made from foam. The port is configured such that rotation of the plate with respect to the port body aligns the opening and lumen defining a passage therethrough for the insertion of surgical instruments.

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit of and priority to U.S.Provisional Patent Application Ser. No. 61/248,035, filed Oct. 2, 2009,the disclosure of which is herein incorporated by reference in itsentirety.

TECHNICAL FIELD

The present disclosure relates to seals for use in surgical procedures.More particularly, the present disclosure relates to a seal anchormember adapted for insertion into an incision or opening in tissue.

BACKGROUND

Today, many surgical procedures are performed through small incisions inthe skin, as compared to the larger incisions typically required intraditional procedures, in an effort to reduce both trauma to thepatient and recovery time. Generally, such procedures are referred to asendoscopic, unless performed on the patient's abdomen, in which case theprocedure is referred to as laparoscopic. Throughout the presentdisclosure, the term “minimally invasive” should be understood toencompass both endoscopic and laparoscopic procedures.

During a typical minimally invasive procedure, surgical objects, such assurgical access devices, e.g., trocar and cannula assemblies, orendoscopes, are inserted into the patient's body through the incision intissue. In general, prior to the introduction of the surgical objectinto the patient's body, insufflation gasses are used to enlarge thearea surrounding the target surgical site to create a larger, moreaccessible work area. Accordingly, the maintenance of a substantiallyfluid-tight seal is desirable so as to minimize or inhibit the escape ofthe insufflation gases and the deflation or collapse of the enlargedsurgical site.

To this end, various valves and seals are used during the course ofminimally invasive procedures. However, a continuing need exists for aseal anchor member that can be inserted directly into the incision intissue and that can accommodate a variety of surgical objects whilemaintaining the integrity of an insufflated workspace.

SUMMARY

In accordance with various embodiments, the present disclosure isdirected toward a surgical port having a compliant port body having atleast one lumen extending therethrough. A plate may be moveablyconnected to the port body. The plate defines an opening that isselectively alignable with the at least one lumen. The surgical platemay be disposed in a substantial perpendicular relationship to thelumen. The plate may be rotatably moveable relative to the port body.The plate may be disposed on a proximal surface, a distal surface, orboth surfaces of the port body. The plate may be movable through adiscrete number of positions relative to the port body. When the plateis in a first position relative to the port body, all of the at leastone opening of the plate is in complete alignment with the at least onelumen of the port body and when the plate is in a second positionrelative to the port body, less than all of the at least one opening ofthe plate is in partial alignment with the at least one lumen of theport body. The port body may be formed of foam.

In accordance with various example embodiments, the present disclosureis also directed towards a surgical port including a compliant port bodyhaving a lumen extending therethrough. The surgical port includes aplate rotatably disposed relative to the lumen, the plate defining anopening that, at least once in the plate's rotational path, isselectively alignable with the lumen so as to define a passage throughthe lumen and the opening for a surgical instrument. The surgical portmay also include a first structure configured to facilitate rotation ofthe plate relative to a longitudinal axis of the port body. The firststructure may comprise a pin. The surgical port may also include asecond structure configured to maintain the relative position of theplate. The second structure maybe a shoulder disposed at thecircumference of the plate which abuts a retaining shoulder on the bodyof the laparoscopic port. The plate may be located on a proximal surfaceof the port body. The surgical port may also include a second plate, andthe second plate may be located on a distal surface of the port body.The plate and the second plate may be connected to each other so as tobe moveable together relative to the port body. There may be multiplepositions along a rotational path of the plate relative to the body suchthat a unique configuration of lumens therebetween is defined at eachposition. The plate may have a substantially arcuate convex profile. Theplate may have a substantially arcuate concave profile. The plate maydefine an indentation along the circumference of the plate to facilitaterotation of the plate relative to the body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

While embodiments of the present disclosure are susceptible to variousmodifications and alternative constructions, certain illustratedembodiments thereof have been shown in the drawings and will bedescribed below in detail. It should be understood, however, that thereis no intention to limit the embodiments of the present disclosure tothe specific form disclosed, but, on the contrary, the embodiments areintended to cover all modifications, alternative constructions, andequivalents falling within the spirit and scope of the presentdisclosure as defined in the claims.

In the drawings and in the description which follows, in which likereferences numerals identify similar or identical elements, the term“proximal” will refer to the end of the apparatus which is closest tothe clinician during use, while the term “distal” will refer to the endwhich is furthest from the clinician, as is traditional and known in theart.

With reference to FIG. 1, an embodiment of the presently disclosedaccess port is shown. The seal anchor member 100 includes a body 1 whichis a temporary percutaneous implant configured to traverse the skin of apatient. Although the embodiment in FIG. 1 shows a percutaneous implant,it is contemplated that body 1 could traverse any biological barrier toprovide selective communication between the volumes on opposing sides ofthe barrier. These include inter and intra organ barriers as well assystemic barriers within the body. It is further envisioned that thesurgical port presently disclosed may be used in a naturally occurringorifice.

The body 1 of the access port has a generally cylindrical form with aproximal surface 9 having a first diameter 9D and a distal surface 10having a second diameter 10D with a medial plane 11 having a thirddiameter 11D disposed therebetween such that third diameter 11D is lessthan second diameter 10D and first diameter 9D defining a profile whichnarrows near the medial plane and widens at the proximal surface 9 anddistal surface 10, thereby defining a generally hourglass configuration.An example of an access port is disclosed by commonly assigned U.S.patent application Ser. No. 12/244,024, filed on Oct. 2, 2008 which isincorporated by reference in its entirety herein and illustrated in FIG.1 a as seal member 500 extending through an opening W in body tissue T.

Although FIG. 1 shows proximal surface 9 and distal surface 10 asplanar, it is contemplated that the profile of either surface could bearcuate such that the surface is concave to facilitate the placement ofsurgical implements and reduce the likelihood of tearing the surfacewhen instruments are angulated or convex to facilitate the removal offluid from the surface.

It is further contemplated that body 1 is composed of a substantiallycompliant or compressible material such that when body 1 is insertedinto an incision, the tissue disposed along the sides of the incisioncompresses body 1 with the resultant restorative force between body 1and the tissue defining a sealing pressure therebetween. The sealingpressure forms a substantially fluid tight seal with its surroundingtissue which separates the volumes which body 1 traverses, e.g. betweenan insufflated cavity and the extra-corporeal environment.

A plurality of lumens 3, 4, and 5 traverses body 1 parallel to alongitudinal axis “A.” Lumens 3, 4, and 5 may be configured to allowfluid communication between ends 9 and 10 or the insertion of surgicalinstruments (e.g. cannulas, trocars, endoscopes, etc.) therethrough.

As shown in FIG. 1, a plate 2 is disposed on proximal surface 9.Further, plate 2 and has openings 6, 7, and 8 extending therethrough.

As shown in FIG. 2 b, plate 2 may be rotated relative to body 1 aboutthe longitudinal axis “A” to an “open” position wherein openings 6, 7,and 8 and lumens 3, 4, and 5 align defining passages therebetween.

As shown in FIG. 2 a, plate 2 may be rotated relative to body 1 aboutthe longitudinal axis “A” such that the holes 6, 7, and 8 and lumens 3,4, and 5 are configured in a “closed” position wherein no holes alignwith any lumen thereby obscuring the passage previously definedtherebetween.

As shown in FIG. 2 c, plate 2 may be rotated relative to body 1 aboutthe longitudinal axis “A” such that the holes 6, 7, and 8 and lumens 3,4, and 5 are configured in a transition or intermediate position whereinholes 6, 7, and 8 partially align with lumen 3, 4, and 5 therebypartially obscuring the passage previously defined therebetween.

It is further contemplated that there may be a plurality of holes andlumens in a specific arrangement corresponding to a plurality ofpositions along the rotational path of the plate. When so configured,rotation of the plate relative to the body about the longitudinal axis“A” to each unique position defines a unique configuration of passageswhich traverse the port in terms of both number and location of thelumens. For example, the holes disposed the plate and body may bearranged in a pentagon centered at a position other than thelongitudinal axis “A”. Consequently, if the plate is then rotatedrelative to the body about longitudinal axis “A”, there will be a firstposition in which two pairs of holes and lumens on the plate and bodyalign defining two passages therebetween. Similarly, there will be asecond position, in which a different hole and lumen on the plate andbody will align defining only one passage.

It is further contemplated that there may be a spring or other biasingdevice disposed in the port 100 to bias the plate 2 toward a neutralposition when no force is applied such that there is a passage betweenthe plate 2 and body 1 in the neutral position.

Alternatively, there may be a spring or other biasing device disposed inthe port 100 to bias plate 2 toward a neutral position such that when noforce is applied holes 6, 7, and 8 and lumens 3, 4, and 5 do not alignthereby obscuring the passage previously defined therebetween.

In an embodiment shown in FIG. 3 a, a body 1 a has a stepped retainingshoulder 12 configured to abut a stepped ring 13 on a plate 2 a suchthat plate 2 a is retained relative to body 1 while being able to rotaterelative to an axis parallel to a lumen 20 a.

It is further contemplated, as shown in FIG. 3 b, that a plate 2 b has astepped retaining shoulder 15 configured to abut a stepped ring 14 on abody 1 b such that plate 2 b is retained relative to body 1 b whilebeing able to rotate relative to an axis parallel to a lumen 20 b.

It is further contemplated, as show in FIG. 3 c, that a plate 2 c has anangled stepped retaining shoulder 17 configured to abut an angledstepped ring 16 on a body 1 e such that plate 2 c is retained relativeto body 1 c while being able to rotate relative to an axis parallel to alumen 20 c.

It is further contemplated, as show in FIG. 3 d, that there is a pin 18which traverses plate 2 and a body 1 d such that a plate 2 d is retainedrelative to body 1 while being able to rotate relative to an axisparallel to lumen a 20 d.

It is further contemplated, as show in FIG. 3 e, that a body 1 e has asubstantially conical or frustoconical protrusion 19 which traverses aplate 2 e such that plate 2 e is retained relative to body 1 e whilebeing able to rotate relative to an axis parallel to a lumen 20 e.

It is further contemplated, as shown in FIG. 3 f, that a body ifincludes a proximal plate 2 f having hole 8 f, a distal plate 21 havinga hole 23, and a traverse pin 22, and a lumen 20 f. Traverse pin 22couples the movement of distal plate 21 and proximal plate 2 f such thathole 23 is aligned with lumen 20 f when proximal hole 8 f aligns with alumen 20 f defining a passage therebetween.

It is further contemplated that the axis about which plate 2 rotates iseccentric relative to plate 2 and body 1. It is further contemplatedthat, in various embodiments of the present invention, the seal anchormember 100 mat include multiple plates, each plate separately disposedso as to selectively cover and uncover different lumen, therebyproviding a surgeon with additional flexibility, e.g., to cover a firstlumen while leaving an instrument disposed within a second lumen, etc.

The use and function of seal anchor member 100 will be discussed duringthe course of a typical minimally invasive procedure.

Initially, the seal anchor member 100 is inserted into a tissue tractusing known surgical techniques. Either subsequent or prior to theaforementioned insertion procedure, plate 2 on body 1 is configured in afirst position, such that no holes on plate 2 align with any lumendisposed in body 1 thereby obscuring the lumen. In the course of thisprocedure, an operator may rotate plate 2 about the longitudinal axis“A” relative to body 1 into a second position such that one or moreholes on plate 2 correspond to lumens on body 1 to define one or morepassages therethrough. Thereafter, laparoscopic and endoscopic surgicalinstruments known in the art may be inserted into the lumen in order tocarry out a surgical procedure.

During the course of the surgical procedure, an operator may replace orremove the instruments disposed in the port insert as needed.
